#NeurIPS2022 When can we find the Nash equilibrium and overcome the curse of multiagent in offline multi-agent RL? Come to our poster Hall J #539 today at 4pm and Hall J #740 on Thursday at 4pm for more details and Q&A! Paper: arxiv.org/abs/2201.03522 & arxiv.org/abs/2206.00159

Wow! Maybe I should generate some poem for my research topic and put that as the main page for my personal website. 🤩

I am excited about this work and see a large potential of further extending this label efficient framework on more complicated scenarios (OOD, generative task, multimodal)

Active Learning studies how AI best direct humans to provide feedback and annotation. Yet these algorithms have wildly different performances on new datasets, making it impossible to pick the best algo to use in practice. We now have a solution (appearing at NeurIPS 2023) 1/7

In NOLA for NeurIPS Conference! Present two papers and one workshop paper. Excited to chat about RL, control, and robotics. DM if you want to meet up : ) 1. Optimal Exploration for Model-based RL in Nonlinear Systems (arxiv.org/abs/2306.09210). Thu 10:45-12:45pm #1507. TL;DR: Not all

New paper on label-efficient supervised finetuning of LLMs. We address the expensive prompt annotation cost by humans/proprietary LLMs, saving as much as 50% on FLAN V2. Paper: arxiv.org/abs/2401.06692 Work led by: Jifan Zhang Yifang Chen Gantavya Bhatt Arnav Das 1/

Excite to announce that our work on posterior sampling for pure exploration linear bandits will be at #AISTATS2024! arxiv.org/pdf/2310.06069… Our method extends top-two sampling for MAB and hopefully opens up new promising directions for exploration in RL.

Our LabelBench work has been accepted to the DMLR journal🎉 Super smooth experience and highly recommended for anyone working on data centric ML work. Check out labeltrain.ai: our broader set of label efficient learning work More on LabelBench: x.com/jifan_zhang/st…

Check out our latest paper in data selection for #CLIP pretraining! by simply switching from CLIPScore filter to negCLIPLoss filter, we have achieved universal improvements. Our additional techniques have also led us to set a new SOTA on #Datacomp-medium.

Check out our new paper on adapting language models to new user preferences in decoding time! Key idea: Optimality analysis based on Legendre transform shows that greedy logits merging is better!

Sorry for raining on o1’s parade, but the more we train LLMs, the worse they get on generating and understanding captions for the New Yorker cartoons. 🧵on our latest study on humor in AI: •Large gap between AI & top human submissions •Dataset with 250M+ human ratings •New

Happy to share that our paper was accepted to #NeurIPS2024. Hope to see you in Vancouver (if my visa goes smoothly...😀)
